I installed Yakima Q towers on my hard shell. the large threaded knobs along with a flat washer works great. Caulked around the holes I drilled for bolts and ran a bead of caulking around underside of base before securing

I went and got an 02 escape roof rack with the cross bars for 45.00. I am going to mount them with some either a rubber strip on the inside with some over sized washers or an aluminum strip with washers.. I will post pics when it is done. Thanks for the ideas..

I would go a little more than oversized washers. Had a rack rip off the
roof of our old Cherokee when my wife drove it with our MTN BIKES still on
the roof ............ I would not use alum either. Just go to Home Depot/Lowes and look in their metal bin -- you will find something there.
You can also get a cheap metal cutter/saw at Harbor Freight to make it
easier than using a hacksaw and file. NOTE: do not hold the metal in your
hand while drilling either (my D____A_____ son did that) ....

Well it is done - Picked up the 02 Escape Rack with the crossbars and got it installed on the hard top. Thanks to all for the advice. I ended up getting 2 metal strips that run on the inside of the jeep.
